The daily lowdown on books, publishing, and the occasional author behaving badly.

Booker-winning author Hilary Mantel's novels have gotten a sales boost after the firestorm in the U.K. over her comments about Kate Middleton, the Duchess of Cambridge. Mantel said that Middleton is "as painfully thin as anyone could wish, without quirks, without oddities, without the risk of the emergence of character." Media outrage was so severe that even British Prime Minister David Cameron jumped in, saying that although Mantel "writes great books," her remarks were "completely misguided." NPR called it "withering." And the Daily Mail, in characteristically shrill fashion, ran the story on the front page, calling Mantel's essay a "venomous attack." But Mantel's full essay is more nuanced, and some have pointed out that the actual thesis of the piece is that royals should be treated more respectfully by the press. Mantel writes: "I'm not asking for censorship. I'm not asking for pious humbug and smarmy reverence. I'm asking us to back off and not be brutes."
